H Girl,
i've turned them down as i believe it sets too much of a precedent for working too many hours!
Sorry if I'm being slow here but maybe that's the point - that they are actually overstaffed and looking to cut, but first are building a case to counter minimum base rest arguments - "well, we know that people will take less than x hours/days rest because when we paid them, they did it, so now we're just going to demand it and we know you can get by on less base days off".
